To all whom it may concern:

Be it known that I, THOMAS P. BULLARD, a citizen of the United States ofAmerica, and a resident of Roseboro, county of Sampson, and State ofNorth Carolina, have invented certain new and useful Improvements inGreen-Pea-Hulling Machines, of which the following is a full and clearspecification.

The object of this invention is to provide a simple machine, principallyfor domestic use, for removing the hulls from green peas withoutmaterially, if at all, injuring the peas, as more fully hereinafter setforth. This application is a continuation in part of my co-pendingapplication Serial N 0. 231,314., filed April 29, 1918, allowed July 18,1918.

In the drawings- Figure 1 is a vertical machine; and

Fig. 2 is a sectional view taken through the slitting devices on theline 22.

Referring to the drawings by reference characters, A designates anysuitable casin in the top of which is formed an inclined passage a;Within the casing and directly in line with passage a is a wheel I)which is adapted to be driven in any suitable manner, preferably, insmall domestic machines, by a hand-crank 0 attached to the shaft of thewheel I). The periphery of the wheel is provided with a broad groove clwhich forms two annular flanges e and in the bottom of said groove 03 isformed a narrower groove f whose edges or corners are beveled OE andprovided with an annular series of sharp projecting pins 9.

On one side of the wheel, within the easing, is mounted a breast segment6 whose face adjacent the wheel is curved to corre spond with theperiphery of the wheel, this curved face being provided with a V-shapedgroove throughout its length, the width of this breast segment blockbeing such that it enters between the flanges e of the wheel so as toform between the periphery of the sectional view of my wheel a segmentalpassage curvingicorre' spondingly to the periphery of the wheel, thispassage having its upper end substantially coincident with the passage(6, so that peapods may be fed down through the passageway endwisely oneby one and be carried down through said passageway by the rotation ofthe wheel, the sharpened pins 9 prosaid viding the necessary frictionfor forcibly oarrying the pea-pods around through the passage as thewheel rotates. The breast segment is normally pressed toward the wheelby springs f" so as to exert a resilient pressure upon the pods as theyare carried downwardly. The pods being green, they are readily bent toconform to the curvature of the wheel. The breast segment is supportedby said spring f and is maintained in true working relation to the wheelby having, as above set forth, its curved edge embraced by the annularflanges 6 formed on the wheel.

As the pea-pods are carried downwardly through the passageway, they arecentered on the wheel-periphery by the converging or beveled sides ofthe groove 7" in the wheel and the correspondingly converging sides ofgroove it formed in the curved face of the segment. As the pods descendthrough this passageway, they are longitudinally slit by suitablyarranged knives or cutters, and as the slit peas emerge from the lowerend of the throat, the pods are separated from the peas by a suitabledevice consisting desirably of a pair of intermeshing paddle-wheels 2'affixed to shafts j and driven in opposite directions by cog-wheels isdriven from a main gear Z affixed to the shaft of the paddlewheel. Fromthese breaking wheels 2', the pods and peas fall through an opening anin the bottom of the casing, and the pods and peas may be separated byhand or by a suitable apparatus. To insure the slitted pods beingdetached from the pins 9 of the wheel, I provide scraper-bar n whosebeveled end is held resiliently in the groove 7 by means of a spring 0.

For slitting the pea-pods as they pass down through the throat, I mayuse any suitable cutters. In the apparatus illustrated, I employ twoslitting-lmives p, g, the former of which is affixed to a suitable partof the frame of the machine and is normally drawn downwardly by means ofthe aforespring 0, the inner end of this knife being curved to conformto the periphery of the wheel and lying in the bottom of the groove f,the extremity of this knife, where the slitting edge is formed, beingarranged to extend into the throat so that as the peapods pass downthrough the throat they will be carried past the knife and be therebylongitudinally slitted along one side. The other knife 9 is arranged toslit the pod at the opposite side, and for this purpose it is mounted onthe segment and extended through an opening therein so as to extend intothe pod-throat at a point approximately opposite the entry-point of theother knife, this knife 9 being made adjustable by means of athumb-screw 1.

It will be observed that slitting of the pods without injury to the peaswill be greatly facilitated by reason of the fact that the normalpressure against the lines of jointure of the pod-sections tends tobulge the sides of the pods outwardly away from the peas, thereby givingmore room for cuting the pods without cutting the peas, and also tendingto rip the pods along the lines of jointure where the pods are splitwhen they are opened by hand.

The nature and scope of the invention having been thus indicated and itspreferred embodiment having been specifically described, what is claimedas new is:

1. In a green-pea huller, a frame, a wheelmember journaled therein, abreast segment member, means for pressing one member normally toward theother, said segment being provided with a groove which together with theperiphery of the wheel forms a curved passageway or throat for thepeapods, and devices entering said passageway for longitudinallyslitting the pods.

2. In a green-pea huller, a rotary member, a stationary member, andmeans for normally pressing one member toward the other, the juxtaposedfaces of these members being shaped so as to provide a throat orpassageway following the periphery of the rotary member, andpod-slitting means in said stationary member adapted to slit the pods asthey pass through said passageway or throat.

.3. In a green-pea huller, a rotary member, a stationary member, andmeans for normally pressing one member toward the other, the juxtaposedfaces of these members being shaped so as to provide a throat orpassageway following the periphery of the rotary member, andpod-slitting means in said stationary member adapted to slit the pods asthey pass through said passageway or throat, means being provided fornormally forcing the slitting devices inwardly toward the pods.

i. In a green-pea huller, a rotary member, a stationary member, andmeans for normally pressing one member toward the other,

the juxtaposed faces of these members being shaped so as to provide athroat or passageway following the periphery of the rotary member, andpod-slitting means adapted to slit the pods as they pass through saidpassageway or throat, the slitting devices being arranged at oppositesides of the passageway in said stationary member, so as to slitopposite walls of the pod.

5. In a green-pea huller, a frame, a wheel member journaled therein, abreast segment member, means pressing one member normally toward theother, the face of one member being provided with a guiding-groove toreceive the adjacent edge of the other member, both members beingprovided with additional grooves to form a curved passageway or throatfor the pea-pods, and devices entering said passageway forlongitudinally slitting the pods.

6. In a green-pea huller, member journaled therein, a breast segmentmember, means for pressing one member normally toward the other, theadjacent faces of said members being shaped to form a passageway orthroat between them for the passage of the green pea-pods, aslittingknife entering said passageway through the breast segment, andanother slitting-knife mounted on the frame and extending into saidpassageway or throat at the opposite side from the other knife.

7. In a green-pea huller, a frame, a wheel journaled therein andprovided with an annular groove, a slitting-knife mounted on the frameand extending so as to have its inner end he in said groove, theextremity of said knife being sharpened and normally extending to apoint outside of said groove, a breast segment forming with the wall athroat or passageway into which the cutting extremity of said knifeextends.

8. In a green-pea huller, a frame, a pair of cooperating members betweenwhich is formed a throat or passage for the passage of the pod, meansfor pressing one member resiliently toward the other to thus exertpressure on the pod sufficient to bulge the sides of the pod away fromthe peas, and means for longitudinally slitting the podwall while thusdistorted or bulged and while passing through said throat or passage.

In testimony whereof I hereunto afiix my signature.
